Setup

Start Control Plane

do just this:

$ go run src/main.go 

INFO[0000] Starting control plane                       
INFO[0000] management server listening                   port=18000

Run sample_servers

Here I am using dummy json-server a nodejs module. To install json-server, you can follow the steps here [https://www.npmjs.com/package/json-server#getting-started].

IP=`ip -f inet addr show wlp0s20f3 | grep -Po 'inet \K[\d.]+'`
json-server --watch sample_servers/profiles.json --host ${IP} --port 10002

This command will start a server on port 10002, and the requests to this server will be proxied through envoy

Run Envoy

To run envoy, just download a local envoy

docker cp `docker create envoyproxy/envoy:v1.16-latest`:/usr/local/bin/envoy .

Then invoke

./envoy -c dynamic-configuration.yaml -l debug

Access proxy

curl  -H "Host: router.mahendrabagul.io" \
   --resolve  router.mahendrabagul.io:10000:127.0.0.1 \
   --cacert certs/envoy-intermediate-and-envoy-root-ca-chain.crt https://router.mahendrabagul.io:10000/profiles

Check dynamic configuration is being applied to envoy or not.

1. You will need to start a server(you can use the json-server command on the posts.json in sample_servers folder). Once you fire below command,

json-server --watch sample_servers/posts.json --host ${IP} --port 10003

update the ip and port in domains.csv present in root of the project like below.

"192.168.1.14","10003","/posts"

When you will do this, the next iteration will pick up this change and push it to envoy. You will be able to access /posts api from envoy's ip and port.

curl  -H "Host: router.mahendrabagul.io" \
   --resolve  router.mahendrabagul.io:10000:127.0.0.1 \
   --cacert certs/envoy-intermediate-and-envoy-root-ca-chain.crt https://router.mahendrabagul.io:10000/posts
